Abstract

Systems ( 200 ) and methods for energy management in a base station ( 1102 ) on a per service basis are described. In particular, the method includes receiving a request for a service corresponding to a user equipment in an access network ( 102 ), determining a type of the service based on the request, estimating a power consumption value for each phase of the service corresponding to the base station ( 1102 ), and transmitting the power consumption value to a core network ( 108 ). Further, the method includes receiving a power consumption policy associated with the type of the service from the core network ( 108 ), determining a real-time power consumption value of the service corresponding to the base station ( 1102 ), and monitoring the real-time power consumption value corresponding to the base station ( 1102 ) based on the power consumption policy.
